Siete tutti malati comes from the Italian dub of The Simpsons, the long running animated series known for lines that become everyday catchphrases. In Italian the sentence is a blunt way to call a group crazy, and short clips of dubbed dialogue often travel on soundboards because the emotion is clear even for listeners who do not speak the language. Fans share this one as a compact reaction, reusing the familiar Simpsons tone of exasperated humour to comment on arguments, fandom moments and absurd social media posts.
